Mängu

Mängu is the genitive singular form of the Estonian noun mäng, which means game or play. It is used to express "of the game" or to connect nouns in attributive phrases. In Estonian, the genitive singular often marks possession, association, or specification.

Examples of its usage include phrases such as "mängu nimi" (the name of the game), "mängu kestus" (the duration of the game), and "mängu mõju" (the effect of the game). The ending -u is a typical genitive singular ending for this noun class, and the form is common in both spoken and written Estonian when referring to something related to a game.

In contemporary usage, mängu appears across discussions of board games, video games, sports, and play-related studies. It also occurs in literature and journalism when referring to the concept of a game rather than to a specific title.

Orthography and capitalization follow standard rules. As a regular word form, mängu is written in lowercase. When it appears as part of a proper noun or a title, capitalization applies in the same way as for other proper names, so a work or brand named Mängu would be capitalized.
